Application filed Septcmher 13, 1883.

To aZZ whom it may concern.-

Be it known that I,ED\VARD I-I. EISENHART, a citizen of the UnitedStates, and a resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in theArt of Preparing Yarn or Thread for Filling, of which the following is aspecification.

The invention relates to the art of preparing yarn or thread forfilling; and it consists in a process of preparing the yarn, jute, orother material employed as a filling, whereby from a single bobbin orcop any required number of picks of like color may be laid, and thenfollowed by an equal number of picks of a different color, and so on,until the entire bobbin or cop has been consumed.

In describing my invention I will explain the machinery employed and theconseeutive steps followed in attaining the desired end. Ihave employedit extensively in the manufacture of jute carpets, and have demonstratedits entire practicability.

The first and probably the most essential part of the process consistsin the peculiar formation of the hank of jute, yarn, or other materialused as the filling, whereby the parts of the hank may be so formed asto permit of their being independently dyed in diii'ercnt colors, and bewound upon the bobbin or cop so that the colors of given lengths willalternate, as hereinafter described. The hank of material is formed uponthe reel A,illustrated in the accompanying drawings, and the jute orother material of which it is composed is taken by the reel from thespools B.

In carrying out my invention I employ the machinery shown in thedrawings, in which Figure 1 is an end view, and Fig. 2 a frontelevation,0f the reeling apparatus. Fig. 3 is an end view of theshiftingbar H, hereinafter described. Fig. 4 is a detached view of aportion of the reel A, showing the hank of jute after it has been fullywound and its up- (X0 model.)

Any desired number of spools B may be employed, according to the numberof hanks it is desired to form upon the reel at one operation. The reelconsists of the horizontal bars 0, secured upon the ends of the spokesD, which radiate from the aXle E. Upon one of the horizontal bars 0 aresecured two vertical pins, F, and between the reel and the spools isarranged,in the pockets G, the shifting-bar H, which will be providedwith proper guides, through which the material from the spools may pass,in the present instance screw eyes I being employed for that purpose. Ifthe carpet is one yard wide and the reel seventy-two inches incircumference, one length of yarn or jute around the reel will answerfor two picks of the carpet, and two lengths around the reel will answerfor four picks, which is the number of each color that I have usuallyemployed.

In the operation of forming the hanks upon the reel, where the carpet isone yard in width and the reel seventy-two inches in circumference, Ifirst draw the yarn of jute, &c., from the spool B through the guides Ion the shifting-bar II, and wind it twice around the reel 011 theoutside of, say, the left-hand pin F, and then (the pins F now being onthe upper side of the reel) move the bar II toward the right until itsguides I carry thejute between the pins F, and then move it stillfarther toward the right, in order that the jute may be on the outerside of the right-hand pin F, at which time the reel is given two morecoinplete revolutions. Then by the shifting of the bar H toward the leftthe jute is carried between the pins F and. to the left thereof to itsformer position, whereupon the reel will be given two more revolutions,as in the first instance, this alternate operation being continued untila hank of the proper size has been formed upon the reel. The linedescribed by the jute as it is moved between and around the pins F is inthe form of the figure 8, and is illustrated in Figs. 5 and 6, Fig. 5showing the line formed when the bar His first moved from theleft towardthe right, and Fig. 6 that when the bar II is returned to its initialposition.

It will be observed that the hank consists of two parts, a b, connectedata single point, and that the portions of the connecting part (I crosseach other alternately at about their center.

and tying them, substantially as indicated in I Fig. 4. The slatcarrying the pins F is then dropped (that is, the pins as sustainingsaid slat on the ends of the spokes D are withdrawn and the slat allowedto lower) and the hank moved off the reel, after which it is dyed in,

say, two colors, the part a, for instance, being scarlet, and thepart 1) black, the line of di- Vision between the colors being at thecenter of the connecting portion at.

The dyeing may be effected in any convenient manner; but I have usuallyobtained satisfactory results by immersing the part b in the tank ofcolor while the part a is suspended clear of thesame, and then reversingthe position of the parts. After the dyeing has been accomplished andthe hank dried the jute or yarn will be wound upon the spindle to formthe cop, and in this operation the jute, being regularly rewound fromthe hank,will first give off four yards from its side a, which, forconvenience, may be cc isidered black, and then four yards from its twinpart b, which is of scarlet hue. Thus it will be observed that therewill first be four yards wound upon the cop of black, then four yards ofscarlet, and afterward four yards of black again, and so on, the colorsalternating on the cop at the end of every four yards drawn from thehank.

The appearance of the cop when wound is approximately illustrated inFig. 7.

There is nothing more to be done now in the consummation of theinvention but to place the cop in the usual shuttle and allow it totravel the ordinary shuttle-race and lay the weft or filling in thecustomary manner.

It will be plain the color will change in the goods as each four yardsof the jute or yarn is drawn from the hank, and that as one yardconstitutes one pick there will appear in the carpet four picks of onecolor, and then four picks of another color, and this without changingthe shuttle, bobbin, or cop or interrupting the motion of the machine.

It will appear obvious that by the employment of more than two pins F, Imay increase the number of parts in the hank and dye each part with aseparate color, thus producing a hank having more than two colors and acop which will give off the required picks in Various alternating colorsto any extent required.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

The method of preparing the hank of filling material,consisting,essentially, in forming the hank in two or more parts, a definite lengthof material being wound alternately in forming .said parts, securing thematerial where the latter crosses for the purpose of keeping the partsseparated, dyeing the several parts in different colors, and thenre'winding to form a cop, substantially as set forth.

Signed at New York, in the county of New York and State of New York,this 14th day of September, A. D. 1883.
